What it does

Linear Multi Env Setup is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze and enforce separate Linear development, staging, and production credentials, apps, webhooks, data, and rollout controls. Use when one integration runs across multiple environments. Trigger with "separate Linear environments", "stage Linear OAuth app", or "isolate Linear webhooks".

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Designed for Claude Code; live verification requires network access and an approved Linear workspace credential

It sits in Backend & APIs, covering Webhooks and OAuth and OpenID Connect. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • One integration runs across multiple environments
  • With separate Linear environments
  • Stage Linear OAuth app
  • Isolate Linear webhooks

Example prompts

  • “separate Linear environments”
  • “stage Linear OAuth app”
  • “isolate Linear webhooks”
  • “/linear-multi-env-setup”

Requirements

  • A credential in API_KEY
  • A credential in ACCESS_TOKEN
  • Compatibility (from SKILL.md): Designed for Claude Code; live verification requires network access and an approved Linear workspace credential
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Inventory every environment's workspace, OAuth app, callback URL, webhook URL, signing secret, client secret, team access, and data class.
  2. Use separate app registrations and secret references where blast radius or callback ownership differs.
  3. Validate exact callback allowlists, public HTTPS endpoints, environment labels, and least-privilege team access.
  4. Prevent local and pull-request jobs from resolving production secret names or mutation endpoints.
  5. Promote configuration through reviewed manifests while rotating or revoking credentials as separate approved operations.
  6. Test misrouting, stale-secret, rollback, and environment-disable scenarios before production rollout.

What it can do on your machine

Read from SKILL.md and the folder at commit 23ea8d4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • WebFetch
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • linear.app

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • API_KEY
    • ACCESS_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; live verification requires network access and an approved Linear workspace credential

    From compatibility in the SKILL.md frontmatter.

Context cost

Linear Multi Env Setup loads about 1.2k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 493 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Linear Multi-Environment Isolation

Overview

Make environment boundaries explicit so a local test cannot consume production credentials, events, or team data.

Prerequisites

  • The target repository, Linear workspace, environment, and accountable owner
  • Current security, privacy, compliance, capacity, and change-control requirements
  • An approved Linear credential only when a bounded live verification is necessary

Tool Discipline

Use Read, Glob, and Grep to inspect code, configuration, and evidence. Use WebFetch only for current first-party Linear documentation and package metadata. Use Write or Edit only for requested implementation with known target files. Never write credentials, customer content, unrestricted environment output, or unredacted GraphQL variables.

Current Contract

  • OAuth callback URLs are registered on an application, and OAuth webhook settings create a workspace-specific webhook when that app is authorized.
  • Webhook signing secrets and OAuth client secrets rotate independently and take effect immediately for their respective uses.
  • Client credentials must be enabled per OAuth app and app-team access can be changed from the app details page.

Authentication

Use a personal API key only for owner-controlled scripts, OAuth with PKCE for user-delegated applications, or an enabled client-credentials grant for approved automation. Personal keys use Authorization: <API_KEY>; OAuth tokens use Authorization: Bearer <ACCESS_TOKEN>. Store credentials server-side in an approved secret manager.

Treat app approval, team access, scope changes, credential creation, rotation, revocation, and production access as owner-approved actions.

Instructions

  1. Inventory every environment's workspace, OAuth app, callback URL, webhook URL, signing secret, client secret, team access, and data class.
  2. Use separate app registrations and secret references where blast radius or callback ownership differs.
  3. Validate exact callback allowlists, public HTTPS endpoints, environment labels, and least-privilege team access.
  4. Prevent local and pull-request jobs from resolving production secret names or mutation endpoints.
  5. Promote configuration through reviewed manifests while rotating or revoking credentials as separate approved operations.
  6. Test misrouting, stale-secret, rollback, and environment-disable scenarios before production rollout.

Approval Boundaries

Do not create, reveal, rotate, or revoke credentials; authorize an OAuth app; change scopes or team access; create, mutate, archive, or delete workspace data; configure or re-enable webhooks; import or export data; change roles, SCIM, or audit streaming; transmit diagnostics; change paid entitlements; or perform another production mutation without explicit approval from the accountable owner. Keep diagnosis read-only unless implementation was requested.

Output

Return the workspace and team scope, auth mode without credential value, files and contracts inspected, exact operation names, evidence collected, validation result, sensitive fields redacted, remaining risk, accountable owner, approval state, and rollback or next action.

Error Handling

ConditionResponse
Environment shares production secretStop rollout and create an independently owned credential boundary.
Webhook routed to wrong environmentDisable processing, preserve delivery IDs, and reconcile after correcting routing.
Callback mismatchRegister the exact environment callback; never use a broad wildcard.
Config promoted without app accessFail readiness and correct team/app authorization before deploy.

Examples

Use a compact handoff that makes scope, mutation authority, and verification evidence reviewable.

Input:

text
env=staging; workspace=test; oauth-app=staging; webhook=https-approved

Expected handoff:

text
credential-boundary=separate; callback=exact; prod-access=none
